Purpose:
To evaluate clinical outcomes after implantation of new presbyopia-correcting intraocular lens (IOL): Artis Symbiose® (Cristalens Industrie, France).
Setting:
Tertiary referral center, Brest, France.
Design:
Non-comparative prospective interventional study.
Methods:
Patients undergoing bilateral IOL implantation were included. Visual acuity (VA) for distance, intermediate (70cm) and near (40cm) vision were measured. In addition, defocus curves were obtained at 1 and 6months, and a reading speed test was assessed using the Salzburg Reading Desk® (SRD) 3months after surgery. The VF-14 questionnaire was evaluated at 1, 3 and 6months after surgery to measure spectacle independence, and a level of satisfaction questionnaire was completed at the 6-month follow-up visit.
Results:
The study included 48 eyes. Mean postoperative monocular uncorrected VA, for MID and PLUS respectively, was 0.028±0.08 LogMAR and 0.057±0.10 at distance (UDVA), 0.035±0.10 and 0.037±0.09 at intermediate (UIVA), 0.078±0.11 and 0.030±0.10 at near (UNVA). Binocularly, uncorrected VA was -0.022±0.02 at distance, -0.002 at intermediate, and 0.015 at near. The binocular defocus curve at 6months after surgery was above 0 LogMAR between +0.50 D and -2.50 D. The mean satisfaction rate at 6months was 83%.
Conclusion:
The Artis Symbiose® IOL provides functional uncorrected visual acuity at distance, intermediate and near positions, without the need for additional optical aid. It is an effective option in active presbyopic patients, with a continuous and extended depth-of-focus, providing added value compared to trifocal implants.
